RAIL-DRILLING MEANS.

Specification of Letters Patent.

Patented Aug. 12,1913.

Application filed March 17, 1913. Serial No. 754,817.

To all whom t may concern.'

'Be it known that I, MICHAEL REEDY, citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Rail-Drilling Means, of which the following is a specification.

My present invention relates to the drilling of transverse apertures in the webs or railway rails, and it seeks the provision of simple, easily applied and efficient means for utilizing to advantage a railway hand car to actuate a drill bit for the purpose stated.

The invention in all of its details will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a fragmentary view, partly in section and partly in elevation, illustrative of the application of my novel devices to a hand car. Fig. 2 is a plan of the same. Fig. 3 is a detail section illustrating the manner in which I socket a drill bit in the end of the drive shaft of a hand car and hold the bit to the wheel of the car. Fig. 4 is a detail section illustrative of the manner of mounting the clamping screw comprised in my improvements.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The hand car illust-rated may be and prefferably is of the ordinary well known construction in general. Among other elements it comprises a body 1 having a frame bar 2, and also comprises a drive shaft 3 adapted to bear track wheels, one of which is shown in Figs. 1, 2 and 3, and is numbered 4. The shaft 3 may be driven in any approvedmanner so as to rotate the traction wheels 4 and to propel the car on a railway. In Fig. 1 I have shown the shaft 3 as equipped with a pinion 5, and I have also shown a spur gear 6 as intermeshed with the said pinion;

i the said spur gear being designed to be connected with and actuated by the conventional hand lever ordinarily to be found on hand cars.

My invention contemplates supporting one end of the body 1 of the car so as to hold the wheels 4 clear of the track rails when the hand car is to be used for actuating the drill bit as hereinafter described. When the body l is so supported and the hand lever is actuated it will be manifest that the shaft 3 will be rotated ata high rate of speed; also, that at that time the wheels 4 will serve as balance or fly wheels.

In furtherance of my invention I provide in one end of the shaft 3 a socket 7, of angular form in cross-section, and I also provide on the face of the vwheel 4 a holder 8 having an angular aperture 9 coincident with the socket 7. The socket and the holder are designed to receive the angular portion of a drill bit 10, and the holder is provided in order to enable the shaft 3 and the wheel 4 to powerfully rotate the drill bit 10 about its axis, and this without the necessity of making the socket 7 yunduly deep and without the imposition of tortional strain upon the bit. To further hold the bit 10 and preclude tortional strain thereof, I provide the wheel 4 with the bracket 11. This bracket 11 is fixed to the face of the wheel 4 and extends a considerable distance laterally outward therefrom, and it is provided at its outer end with a portion 12 in which is an angular bore conforming to and receiving the angular portion of the bit 10. Also in furtherance of my invention, I employ a frame for holding a railway rail in proper relation to the hand car during the drilling of an aperture in `the web-of the rail. The said frame comprises a bar 13, preferably of wood, arms 14, preferably of metal, pivoted at 15 to the bar 13 and having depressed portions 16 adjacent the bar 13 and also having upwardly reaching portions 17 and terminals 18 extending outwardly from the portions 17, a nut 19, Figs. 2 and 4, mounted in the bar 13, and a clamping screw 20 extending through the bar 13 and the nut 19 and bearing in the latter.

In the practical use of my improved means, the rail 21 to be drilled is supported at a suitable elevation above the road bed of the railway, and the body 1 of the hand car is raised and supported in raised position so as to hold the wheels 4 on the shaft 3 clear of the railway rails. The frame is then positioned as shown in Figs. 1 and 2- z'. e., the hooks at the inner ends of the arms 14 are engaged with the car frame, and the bar 13 is positioned at the opposite side of the rail 21, with reference to the car; the rail rest-ing on the arms 14 of the frame. The screw 2O having been turned against the outer side of the rail web, and the drill bit l having been positioned in the socket and holders ot the wheel, the hand lever otI the car is actuated whereupon the drill bit will be powerfully rotated at a high rate of speed. As the drilling progresses7 the screw 2O is turned up and in that way the rail 2l is presented to the drill bit l0 until the transverse aperture is completed through the web of the rail, when the screw is retracted and the rail 2l shifted to proper position for the formation of another aperture.

Subsequently to the boring of apertures in the web ot the rail t'or the connection of lishsplates or tor any other purpose, the frame comprisiilg the bar 13 and the arms lst is removed from the rail and the car frame, and is carried upon the car for subsequent use. The drill bit is also removed from the holding' means and placed upon the cur, and then the car is lowered to place the traction Wheels Ll on the rails, when the ear can be moved with the same facility as an ordinary hand car to another point where work is to be done.

It will be gathered from the foregoing that my novel equipment is simple and inexpensive in construction, and that it does not impair the general usefulness of the car.

Having described my invention, what I claim and desire to secure by IiettersPatent, is:

l. In means for the purpose described, the combination of a hand car having a glrive-shaft and a traction wheel thereon and also haring a socket, of angular form in cross-section, in the socket., a holder tixed to the outer tace of the Wheel and having an aperture, of angular form in cross-section, coincident with said socket, a bracket fixed to the face of the wheel and having a holder portion in its outer end in which is an aperture coincident. with the tirst named aperture and said socket and a frame comprising a bar and arms connected to the bar and having hook port-ions adapted to be engaged with the trame ot the ear, a drill for use in the socket and holders, and

a clamping screw carried by the bar and adapted to bear against. the outer side of a rail, with reference to the drill bit.

2. In means for the purpose described, the combination of a hand car having a driveshaft and a. traction wheel thereon and also having a socket in one end of the driveshaft, means on the wheel for holding a drill bit, a iframe constructed and arranged to be detachably connected with the car and having a portion disposed to be positioned at the opposite side of a rail with reference to the car, a bit adapted to be positioned in the socketl and holding means of the shaft and Wheel, and a clamping screw mounted in the portion of the frame at the opposite side of the rail to the car.

3. In means for the purpose described, a hand car having a driveshaft and a traet-ion Wheel thereon, drillbit-h0lding means on the wheelj a drill bit removably arranged in said means, a frame constructed and arranged to be detachably connected with the car and having` a portion disposed to be lo cated at the opposite side of a rail with reference to the ear, and means carried by said portion for presenting a rail to the drill bit.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
